In the sacristy there is an admirable bust, by Benedetto da Maiano, of Onofrio di Pietro, the Operaio of the Collegiata under whose superintendence the building was restored and the shrine of Santa Fina constructed; he died in 1488. The marble ciborium is also by Benedetto. A Madonna and Child with six Saints by Sebastiano Mainardi does not show that painter at his best. Out of the left aisle opens the chapel of San Giovanni, with a frescoed Annunciation of 1482, probably executed by Mainardi from the design of Ghirlandaio, and an old baptismal font (still used) made by Giovanni Cecchi of Siena in 1379 at the expense of the Arte della Lana, with quaint bas-reliefs of the Baptism of Christ, Angels and the _Agnus Dei_ of the Guild. This same Guild, together with the Commune, had previously borne the cost of Bartolo di Fredi's frescoes. There is a cloister attached to the Pieve with a few remains of frescoes, one of which--a Pietà--is ascribed by Mr Berenson to Pier Francesco Fiorentino. At the side of the Collegiata is the Palazzo Comunale or Palazzo del Popolo, which was begun in 1288. Its great tower, the Torre del Comune, was begun in 1300 and finished about 1311, when the bell of the Commune was placed there. The palace is sometimes called the new Palazzo del Podestà, because after 1353 the Florentine Podestà resided here. The steps lead up to the platform upon which the Podestà stood when he presented his credentials and received the baton and keys from the Gonfaloniere, and it was at its steps that the two Ardinghelli had been beheaded in 1352. There is a picturesque court, with fragments of frescoes and armorial bearings, and a well of 1360. To the right of the court is what was once the Cappella delle Carceri. Opposite the door is a fresco of the Madonna and Child enthroned, with St Geminianus and another bishop, of the school of Taddeo di Bartolo. By Bazzi (hastily executed and much repainted) are frescoes in chiaroscuro, representing St Ivo, the just young judge, administering justice to the poor and helpless, and, at the foot of the stairs, a magistrate seated between Truth and Prudence, trampling upon the Lie.
